Neuronal mechanism underlying dystonia poorly understood and no effective treatment for every patient with dystonia has been found yet. Our study aimed to develop a novel treatment using brain-machine interface system that changes stability of neural circuits in the cortex by bypassing brain and external world without the normal neuromuscular pathway. To achieve this purpose, we recorded electroencephalograms (10 channels) and forearm electromyograms (3 channels) from 2 patients with the diagnosis of writer's cramp as a preliminary experiment. In the analysis, a time-frequency representation of each electroencephalographic signal and coherence between electroencephalographic and electromyographic signals were computed. Comparing to the patients with dystonia (not writer's cramp) and healthy subjects, the result clearly shows a prominent of electroencephalographic activity in specific frequency band where is functional coupling between cortical activity and electromyograms during sustained contractions.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"40995","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HASHIMOTO, Yasunari","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"40996","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OTA, Tetsuo","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人電子情報通信学会"}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2012 IEICE"}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"橋本, 泰成","creatorNameLang":"ja"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"大田, 哲生","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"No148.pdf","filesize":[{"value":"379.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"No148.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/7926/files/No148.pdf"},"version_id":"039e7772-4696-41db-bbea-96506ebfc4a0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"脳波","subitem_subject_scheme":"Other"},{"subitem_subject":"筋電図","subitem_subject_scheme":"Other"},{"subitem_subject":"コヒーレンス","subitem_subject_scheme":"Other"},{"subitem_subject":"electroencephalogram","subitem_subject_scheme":"Other"},{"subitem_subject":"electromyogram","subitem_subject_scheme":"Other"},{"subitem_subject":"Coherence","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"局所性ジストニアにおける脳波スペクトル解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"局所性ジストニアにおける脳波スペクトル解析","subitem_title_language":"ja"},{"subitem_title":"Spectral analysis of electroencephalogram in focal hand dystonia","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-08-24"},"publish_date":"2015-08-24","publish_status":"0","recid":"7926","relation_version_is_last":true,"title":["局所性ジストニアにおける脳波スペクトル解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:21:23.959870+00:00"}
